From 715e4cd405cfd67bd058e410b3e599bab2072645 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Thu, 13 Nov 2014 14:40:37 +0800 Subject: libceph: specify position of extent operation allow specifying position of extent operation in multi-operations osd request. This is required for cephfs to convert inline data to normal data (compare xattr, then write object).
